IMPROVEMENT IN sKATEs.

Specification forming part of Letters Patent No. 160,087, dated February23, 1575; application liled December 28, 1874.

To all whom it may concern:

Be it known that I, REGINALD H. EARLE, of St. John, in the Province ofNewfoundland, have invented a new and useful Improvement in Skates, ofwhich the following is a specication:

Figure l is a bottom view of one of my irnproved skates. Fig. 2 is aside view of the same. Fig. 3 is a detail cross-section of the same,taken through the line w x, Fig. 1. Fig. 4 is a detail cross-section ofthe same, taken through the line y y, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has for its object to simplify the construction of theskate for which Letters Patent No. 155,015 were granted to me September15, 1874, make it more convenient in use, and enable it to be applied toany kind of a boot or shoe.

The invention consists in the combination of the screws and their diskswith the sliding arms, the slotted sliding plate, and the footplate; inthe rearwardly-projecting edge or teeth formed upon the rear end of thesliding plate, in combination with the sliding heelplate and thestationary heel-plate and in the combination of the arm with the longarm of the lever that operates the clamps, and with the instep-strap, ashereinafter fully described.

A represents the blade or runner of the skate, to the upper edge of theforward part of which is secured a plate, B, upon which the forward partof the skaters foot rests. To the upper edge of the rear part of theblade A is attached a plate, C, to support the heel of the skaters foot.Upon the under side of the foot-plate B is formed a transversedovetailed or T groove to receive the sliding arms D, the outer ends ofwhich are bent upward, and are corrugated, to clasp the edges of theboot-sole. Through screw-holes in lugs formed upon or attached to thelower side of the outer part of the sliding arms D are passed the screwsE, the outer ends of which are squared off to receive a key for turningthem. To the inner ends of the screws E are attached small disks e',which enter inclined slots fl formed in the forward part of the plate F.

By this construction, by turning the screws E the arms D may be movedout and in, to

adjust them to the width of the boot-sole to which the skate is to beattached. By moving the plate F forward, to bring the disk c into therear part of the slots f1, the arms D will be moved outward to releasethe bootsole; and by moving the plate F to the rearward, to bring thedisks e into the forward parts of the slots f1, the arms D will be movedinward, to clasp the edges of the boot-sole and secure the skate to it.

The middle forward part of the plate F has a longitudinal slot, f2,formed in it to receive the stud by which the plate B is secured to theblade A. The rear part of the plate F is made narrow, and extends backso as to overlap the forward part of the heel-plate O. The rear end f3of the plate F is bent upward at right angles, and has arearwardly-projecting edge or teeth formed upon it, to take hold of thefront side of the boot-heel. Upon the heelplate C is placed a plate, G,upon the rear edge of which are formed upWardly-projectin g lugs g1, theinner sides of which are corrugated, and against which the rear side ofthe boot-heel rests. Through a screw-hole in a lug, g2, formed upon orattached to the rear part of the lower side of the plate G, passes thescrew H, the rear end of which is squared off to receive a key forturning it. The forward end of the screw H is swivelcd to the stud bywhich the heel-plate C is connected with the blade A, so that by turningthe said screw H the plate G may be slid forward and back upon the plateC, to adjust it to the size of the heel of the boot to which the skateisL to be applied. The plate G is kept in place, as it is slid back andforward, by the lug g2 and olie or more rivets, g3, which pass throughslots in heel-plate O, as shown in Fig. l. I is a bent lever, which ispivoted at its bend or angle to the heel-plate O, and the end of theshort arm of which is pivoted to the rear end of a short connecting-bar,J. The forward end of the connecting-bar J is pivoted to the rear partof the sliding plate F, the pivotingrivet passing through a slot in theforward part of the heel-plate O,to cause the plate F to move in astraight line.

By this construction, by moving the long arm of the lever I outward thesliding plate F is moved forward, which releases the skate from theboot; and by moving the long arrn of the said lever I inward the slidingplate F is moved to the rearward, clamping the skate to the boot.

The free end of the long arm of the lever I, when moved inward, catchesupon a catch, K, attached to the foot-plate B. To the inner edge of theforward. part of the long arm of the lever I is attached, or upon it isformed, an arm, L, the forward end of which is slightly concaved, so as,when the lever I is moved inward, to press against and tighten the strapM, which passes through a hole in the middle part of the blade A andover the instep of the foot.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent- 3. The combination of the arm L with the A lever I,that operates the clamps, and with the instep-strap M, substantially asherein shown and described'.
